I have recently bought a bottle of acetone from my local hardware store. When I opened the bottle, I was surprised about the absence of the strong smell of acetone. Only then I discovered the smaller printed words "Eco replacement" on the label:
On the backside, the bottle indicates the constituents as:
- < 10 % anionic surfactants
I compared the chemical composition and characteristics of 2-Butoxyethanol and acetone. To the eyes of a non-chemist, they are very distinct substances. Both are very good solvents, 2-butoxyethanol seems less toxic than acetone. I am happy to believe that 2-butoxyethanol can replace acetone for very many applications, but I fail to find any application notes about 2-butoxyethanol as an acetone replacement.
My question is about the limits. Are there applications where 2-Butoxyethanol fails to replace acetone?
If this is too broad as a question, I would like to narrow it down to the two applications that I am really interested in:
- use as a cleaner before applying glass fiber reinforced resins (epoxy or polyester). Acetone is usually used because it solves many polymers, but leaves polyester intact.
- use to "rejuvenate" PEI (polyetherimide) coated heat beds for 3D printing. The materials to be removed from such heat beds are the printing materials (including PLA, PETG, and ABS), as well as glue stick residues, and body grease.
Is 2-Butoxyethanol a good choice for these uses?
